404 - Page Not Found

The page that you are looking for could not be found. I recently switched to a new content management platform so some of the old links no longer work. Below are the search results based on the link that you clicked on.

Quick vim tip: Copying matching lines to the end of file

I recently had the need to cleanup a long diff file and move certain lines to the end of the file for further analysis. The diff file that I got was something like the following, only much longer (produced using diff -qr xxx yyy).

Files xxx/abc1 and yyy/abc1 differ
Only in xxx: cde1
Files xxx/abc3 and yyy/abc3 differ
Files xxx/abc4 and yyy/abc4 differ
Only in xxx: cde2
Only in xxx: cde5
Files xxx/abc5 and yyy/abc5 differ
Only in xxx: cde3

I didn’t care as much about the “Only…” lines, but the files that differed needed more attention. To accomplish this I wanted to get this file in the following format.

Only in xxx: cde1
Only in xxx: cde2
Only in xxx: cde5
Only in xxx: cde3
Files xxx/abc1 and yyy/abc1 differ
Files xxx/abc3 and yyy/abc3 differ
Files xxx/abc4 and yyy/abc4 differ
Files xxx/abc5 and yyy/abc5 differ

I could go in and copy and paste all the lines that matched, but that would be a lot of manual work. So, I looked around for a minute and came up with the following command.

:%g/^Files/m$

Vim is awesome!
